[0079] The following describes in detail various embodiments of the present invention in conjunction with the accompanying drawings.

[0080] See also Figure 1 The embodiment of the utility model provides a coating auxiliary device 100, which is used to carry a workpiece and can be placed together with the workpiece in a coating machine to form a thin film on the surface of the workpiece through a plasma enhanced chemical vapor deposition process. The workpiece can be a mobile phone middle frame, etc.

[0081] See also Figures 1 to 3The coating auxiliary device 100 includes a bracket 110, an auxiliary mechanism 120 and a bearing member 130. The bracket 110 includes a top seat 111 and a base 112 which are arranged opposite to each other, and a connecting member 113 which is respectively connected to the top seat 111 and the base 112. A positioning groove 112a is provided on the side of the base 112 facing the top seat 111. The auxiliary mechanism 120 includes a loading seat 121, a rotating member 122 and a limiting member 123. The loading seat 121 is inserted into the top seat 111. The rotating member 122 is passed through the loading seat 121 and is rotatably connected to the loading seat 121. A receiving groove 122a is provided on the side of the rotating member 122 facing the base 112. The limiting member 123 is connected to one end of the rotating member 122 and is located between the rotating member 122 and the base 112. The limiting member 123 is provided with a clamping hole 123a. The receiving groove 122a, the clamping hole 123a and the positioning groove 112a are coaxially arranged. The carrier 130 is used to carry the workpiece. One end of the carrier 130 is inserted into the positioning groove 112a, and the other end of the carrier 130 is clamped in the clamping hole 123a and extends to the storage groove 122a. The base 112 drives the carrier 130 to rotate, so that the carrier 130 drives the rotating member 122 to rotate relative to the loading seat 121 through the limiting member 123.

[0082] In the above-mentioned coating auxiliary device 100, when one end of the carrier 130 rotates with the base 112, the other end of the carrier 130 drives the rotating member 122 to rotate through the limit member 123, and the loading seat 121 rotatably connected to the rotating member 122 is inserted into the top seat 111, and the receiving groove 122a, the clamping hole 123a and the positioning groove 112a are coaxially arranged, which can reduce the amplitude of the eccentric rotation of the end of the carrier 130 away from the positioning groove 112a during the rotation process, so as to improve the coaxiality of the upper and lower ends of the carrier 130 during the rotation process, thereby facilitating improving the coating uniformity of the workpiece located on the carrier 130.

[0083] See also Figures 3 to 5 In some embodiments, the loading seat 121 includes a loading member 1211 and a bearing 1212. The loading member 1211 is inserted into the top seat 111 and is provided with a loading slot 1211a and a mounting slot 1211b. The loading slot 1211a penetrates the loading member 1211, and the mounting slot 1211b is provided on the side wall of the loading slot 1211a. The bearing 1212 is embedded in the mounting slot 1211b and sleeved on the rotating member 122.

[0084] Therefore, the bearing 1212 is sleeved on the rotating member 122 so that the rotating member 122 can rotate relative to the loading seat 121 , which has a simple structure and low manufacturing cost.

[0085] In some embodiments, a side wall of the mounting groove 1211b is provided with an annular groove 1211c, and the loading seat 121 further includes a loading snap ring 1213, which is received in the annular groove 1211c and supports the bearing 1212 to the bottom wall of the mounting groove 1211b.

[0086] In this embodiment, the bearing 1212 is matched with the mounting groove 1211b, so that the bearing 1212 can be quickly assembled into the mounting groove 1211b. The loading snap ring 1213 can form a stopper for the bearing 1212 in the axial direction of the bearing 1212, so as to prevent the rotating member 122 from driving the bearing 1212 to move along the axial direction of the bearing 1212 during the rotation process, thereby improving the rotation stability of the rotating member 122.

[0087] In some embodiments, there are two mounting grooves 1211b, two annular grooves 1211c, two bearings 1212 and two loading retaining rings 1213. The two mounting grooves 1211b are located between the two annular grooves 1211c. The two bearings 1212 correspond one-to-one to the two mounting grooves 1211b. The two loading retaining rings 1213 correspond one-to-one to the two annular grooves 1211c.

[0088] In this embodiment, along the axial direction of the bearing 1212 , the arrangement order of the above components is the loading retaining ring 1213 , the bearing 1212 , the bearing 1212 and the loading retaining ring 1213 .

[0089] Therefore, the two bearings 1212 and the two loading retaining rings 1213 can limit the rotating member 122 at the upper and lower positions of the rotating member 122 , which can further improve the stability of the rotation of the rotating member 122 .

[0090] See also Figure 3 and Figure 4 In some embodiments, the rotating member 122 includes a rotating body 1221 and an outer body 1222. The rotating body 1221 is inserted into the bearing 1212 of the loading seat 121 to be rotatably connected with the loading seat 121 through the bearing 1212. The receiving groove 122a is provided on a side of the rotating body 1221 facing the base 112. The outer body 1222 is connected to the peripheral side of one end of the rotating body 1221 close to the base 112 and is connected to the stopper 123.

[0091] Therefore, the outer body 1222 and the rotating body 1221 form a T-shaped structure, which is convenient for assembling the rotating member 122 to the loading member 1211 by driving the outer body 1222. In addition, when assembling the rotating member 122 to the loading member 1211, the outer body 1222 can abut the loading member 1211 to limit the position of the rotating member 122.

[0092] In some embodiments, the receiving groove 122a includes a rotating groove 122b and a guiding groove 122c. The guiding groove 122c is formed on the side of the rotating body 1221 of the rotating member 122 facing the base 112, and the inner diameter of the guiding groove 122c gradually decreases in the direction away from the base 112, and the rotating groove 122b is formed on the bottom wall of the guiding groove 122c, and the side wall of the rotating groove 122b is clearance-matched with the bearing member 130 extending into the rotating groove 122b.

[0093] Therefore, the guiding groove 122 c is substantially in a conical structure, and can guide the carrier 130 to extend into the rotating groove 122 b , which is beneficial to improving the storage efficiency of the storage groove 122 a for one end of the carrier 130 .

[0094] See also Figure 3 and Figure 4 In some embodiments, one end of the rotating body 1221 of the rotating member 122 away from the limiting member 123 protrudes out of the loading member 1211 of the loading seat 121, and the auxiliary mechanism 120 also includes a covering member 124, which is sleeved on one end of the rotating body 1221 of the rotating member 122 away from the limiting member 123 and is spaced apart from the loading member 1211 of the loading seat 121 to cover the loading slot 1211a.

[0095] Therefore, the cover member 124 covers the loading slot 1211 a to prevent external objects, such as dust, liquid, etc., from entering the loading slot 1211 a, so as to avoid damage to the bearing 1212 and the loading retaining ring 1213.

[0096] In some embodiments, a stop groove 1221a is opened on the peripheral side of one end of the rotating body 1221 of the rotating member 122 away from the limiting member 123, and the auxiliary mechanism 120 also includes a stop snap ring 125, which is sleeved in the stop groove 1221a and supports the covering member 124 to the rotating body 1221 of the rotating member 122.

[0097] Therefore, the stop ring 125 can stop the cover member 124 in the axial direction of the bearing 1212, thereby improving the stability of the cover member 124 in covering the loading slot 1211a.

[0098] See also Figure 2 and Figure 4 In some embodiments, the position limiting member 123 includes a position limiting body 1231 and a height limiting body 1232. The clamping hole 123a passes through two opposite sides of the position limiting body 1231, and two ends of the height limiting body 1232 are detachably connected to the position limiting body 1231 and the rotating member 122, respectively.

[0099] In this embodiment, there are two height limiting bodies 1232, and the two height limiting bodies 1232 are symmetrically arranged on opposite sides of the clamping hole 123a. One end of each height limiting body 1232 is detachably connected to the limiting body 1231 by clamping cooperation, and the other end of each height limiting body 1232 is detachably connected to the outer edge body 1222 of the rotating part 122 by bolts.

[0100] Therefore, the support member 130 can be limited in the length direction of the support member 130 by the height limiting body 1232, which is helpful to reduce the deflection and floating of the support member 130 during the rotation process.

[0101] See also Figure 1 and Figure 6 The top seat 111 is provided with a support hole 111a, which is provided on the side of the top seat 111 and penetrates the upper and lower surfaces of the top seat 111, so that the support hole 111a is an open through hole. The loading member 1211 is inserted into the support hole 111a and abuts against the hole wall of the support hole 111a, so that the top seat 111 forms a support for the loading member 1211. In this embodiment, the support hole 111a and the positioning groove 112a are coaxially arranged.

[0102] In this embodiment, the cross-sectional area of ​​the lower end of the loading member 1211 is smaller than the cross-sectional area of ​​the upper end of the loading member 1211. When the auxiliary mechanism 120 is loaded onto the top seat 111, the auxiliary mechanism 120 is first driven to move to the side of the support hole 111a, and the support hole 111a is located between the rotating member 122 and the loading member 1211, and then the loading member 1211 is translated until the lower end of the loading member 1211 enters the support hole 111a, and finally, the loading member 1211 is driven to move downward until the side surface of the upper end of the loading member 1211 abuts against the side wall of the support hole 111a.

[0103] See also Figure 1 and Figure 7 In some embodiments, the base 112 includes a bottom plate 1121 and a driving member 1122. The bottom plate 1121 is arranged opposite to the top seat 111 and connected to the connecting member 113. The driving member 1122 includes a driving body 1122a and a positioning body 1122b. The driving body 1122a is arranged on the bottom plate 1121, and the positioning body 1122b is connected to the side of the driving body 1122a facing the top seat 111. The positioning groove 112a is provided on the side of the positioning body 1122b facing the top seat 111. The driving body 1122a is used to drive the positioning body 1122b to drive the bearing member 130 to rotate. In this embodiment, the driving body 1122a is a rotary cylinder.

[0104] See also Figure 7 In this embodiment, the positioning groove 112a includes a base groove 112b and a clamping groove 112c opened on the side wall of the base groove 112b.

[0105] See also Figure 8 In this embodiment, the carrier 130 includes a string rod 131, a carrier body 132, two guide bodies 133, a clamping body 134 and a pressing body 135. The top of the string rod 131 is cylindrical to be received in the receiving groove 122a, the bottom of the string rod 131 is cylindrical to be received in the base groove 112b, and the middle part of the string rod 131 is roughly square. Correspondingly, the clamping hole 123a is also square, so that the string rod 131 is clamped in the clamping hole 123a. The supporting body 132 is sleeved and fixed on the bottom end of the string rod 131 to carry the workpiece. The two guide bodies 133 are connected to the supporting body 132 to guide the workpiece to be arranged in a stacked form on the supporting body 132. The clamping body 134 is passed through the bottom end of the string rod 131 and clamped in the clamping groove 112c to fix the string rod 131 to the positioning body 1122b, and the pressing body 135 is movably clamped on the string rod 131 to press the workpiece onto the supporting body 132.

[0106] The process of assembling materials in the coating auxiliary device 100 described in the above embodiment is roughly as follows:

[0107] First, assemble the auxiliary mechanism 120, and stack the workpieces onto the string rod 131 and place them on the carrier 132, and hold the workpieces with the holding body 135;

[0108] Then, the carrier 130 loaded with the workpiece is driven to move until the clamping body 134 of the carrier 130 is clamped in the clamping groove 112c;

[0109] Finally, the auxiliary mechanism 120 is driven to move to the side of the support hole 111a, and the support hole 111a is located between the rotating member 122 and the loading member 1211, and the auxiliary mechanism 120 is translated until the lower end of the loading member 1211 enters the support hole 111a. Finally, the loading member 1211 is driven to move downward until the side surface of the upper end of the loading member 1211 abuts against the side wall of the support hole 111a. During this process, the upper part of the string rod 131 is clamped in the clamping hole 123a and extends to the receiving groove 122a of the rotating member 122.
